Hi everyone,
I’m currently working on a home energy monitoring setup using ESP32 and multiple SCT-013 CT sensors. I’ve managed to get real-time current readings using EmonLib, but I’m noticing inconsistent values when more than two CTs are connected at the same time.
I’ve checked calibration and ADC sampling rates, but I’m still seeing a ±10% fluctuation between readings. I suspect it might be due to interference or grounding issues.
Setup Details:
ESP32 Dev Board
3x SCT-013-000 CT sensors
Burden resistors as per EmonLib recommendation
Running on 5V USB power
Has anyone here tried a multi-CT setup on ESP32 and achieved stable results? Would love to hear your experience or suggestions.

Looking forward to your insights!
